The surveys found overall Clinton's margins over GOP candidates had dropped since early February in the wake of questions over her use of personal email while secretary of state.

Jeb Bush was the only GOP candidate to top Clinton in Florida, where he was backed by 45 percent of respondents and she was supported by 42 percent. Walker trailed her 46-40.

In Ohio, Rand Paul was Clinton's closest challenger, and she led him 46-41. She led Walker 49-38.

In Pennsylvania, 45 percent backed Paul to 44 percent for Clinton. She topped Walker there 46-41.

The polls were conducted March 17-28 via live interviews over land lines and cell phones. More than 1,000 surveys of voters were conducted in each state, and the margin of error for each sample was plus or minus 3 percentage points.
